MARTIN S. SWANSTROM, OF GI-IICAGO, ILLINOIS.

SPRING-SUPPORT FOR BEDS.

- Specification of Letters Patent.

Application filed. January 6, 1911. Serial No. 601,154.

To all whom it may concern:

Be it known that I, MARTIN S. SWAN- STROM, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in S pring-Supports for Beds, of which the following is a specification. I

My invention relates to spring supports for beds, couches and the like, and has for its object improvements in such devices.

In the accompanying. drawings Figure 1 is a side elevation of my invention applied to a bed; and Fig. 2 is an elevation at right angles to Fig. 1, parts being shown in section.

In the said drawings A, A and A are parts of an ordinary metallic bed-stead and B, B and B are parts of an ordinary woven wire spring bed. On the angle iron B is secured a bracket G which in ordinary use is intended to rest upon the bracket A of the bed. I. however, insert a spring support between the bracket A and the bracket C,

which spring support is made adjustable under each corner of the bed so that the bed itself may be held at a desired position.

Resting partly on the bracket A and partly on a filler A of some soft material like wood or leather on the side rail A is a tubular standard D provided with a flange D Both E and clamping plate F serve as a means for securing standard D at a desired position on bracket A The upper part of the standard D is slotted as shown at D for the admission of a bracket C of the bed. Inside of the tubular standard D is an ordinary helical spring S on the top of which are washers IV, and on top of the washers is a nut N screwed upon a bolt H, the head of each one of which serves as a direct support for the bracket C. It will be evident from the construction shown that weight placed upon the bed will cause a compression of the spring S, which sprlng is in a simple form and. of the kind best capable of sustaining compression. It will also be evident that by adjusting the position of the screw N on the bolt II that the tension of the spring S under the bracket C may be'varied as desired. In an ordinary bed there are four of these standards D with their associate parts, one being under each corner of the bed. By adjusting the nuts N at the various corners desired tension may be produced upon the difierent Patented Oct. 10,

springs or the bed may be brought to either I a level or a particular desired incline. Also a certain amount of adjustment may 'be made by shifting one or more of the washers IV from position over a spring at one corner to a spring at another corner. In the case of abed the greater part of the weight is at one end when it is being used to sleep in, and to accommodate such difierence -I make it a practice of using springs S of a slightly greater stiiiness in two of the stand ards than in the other two. By this means the bed canbe maintained at a particular level both when it is empty and when it'is occupied. V

The bed-stead and the bed are of the kind commonly used and for the purpose of-enabling the support which I have provided,

being located at a position which will adapt it to beds having the brackets O at different locations, it will be seen that the bracket is adjustable to various positions on thebedstead. Thus if thestandards be fixed on the bed-stead for one bed and it be desired to substitute therefor another bed having its brackets C somewhat diflerently located, this different location can be accommodated by shifting the standards D by means of their clamping devices E and F. It will also be observed that the spring S rests loosely inside the standards D andmaybe easily removed by reaching through the slot D and another spring substituted therefor in case the spring becomes weakened through use.

What I claim'is:

1. The combination with the pro ections extending from a bed, of a tubular standard for each projection, into which standard the projection extends, a coil spring within each stead, and projections extending from thebed, of a tul-nilar standard secured to the bedstead be" each projection. a spring within each standard serving as a yielding support for the corresponding projection, and means for adjusting the tension of each spring under the supported projection.

a. The combination with a bed, a bedstead, and projections extending from the bed, of a standard secured to the bedstead beneath each projection, a spring inclosed by each standard and serving as a yielding support of the corresponding projection, and a screw for adjusting the tension of each spring.

5. The combination witha bed and a bedstead, of a'hollow standard secured to the bedstead under, each corner of the bed, a helical spring located inside of each standard, and a projection secured at each corner of the bed, said projections being adapted to enter the open upper ends of the standards and to be supported by the springs inclosed therein.

The combination with a bed, and a bedmo ns stead, of a standard secured to the bedstead under each corner of the bed, and a' spring in each standard serving as a supportfor the corresponding corner of the bed, the springs in two of said standards being slightly stifiier two standards for the purpose specified.

7 The combination with a bed, a bed stead, and lateral projections secured to the bed, of a tubular standard secured to the bedstead under each projection and provided with a transverse slot for the reception of the projection, and ahelical spring located in each standard and serving as a yielding support of the corresponding projection.
